Abstract
Lac repressor headpiece (HP) and intact lac repressor have been studied using the photo-CIDNP method. At neutral pH histidine 29, tyrosines 7, 12 and 17 and methionine 1 are polarised. His-29 polarisations are weaker and broader in HP59 than in HP51 indicating that the C-terminal octapeptide in HP59 adopts a
